Well my front bumper has seen better days. I guess even with the clear bra, the constant abuse over the years it has started to form spider cracks around all the openings. I think its time to replace it. Does anyone know if the RK Sport from bumper is polyurethane? or is it fiberglass?. I really want to stay away from fiberglass front bumpers, because they just dont hold up like poly does. Any suggestions?
